IMPROVEMENT IN CULINARY BOILERS.

Specification forming part of Letters Patent No. 172,096, dated January11, 1876; application filed November 17, 1875.

To all whom it may concern:

Be it known that I, ALBERT T. DOSTER, of Bethlehem, in the county ofNorthampton and State of Pennsylvania, have invented certain new anduseful Improvements in (Julinary Utensils; and do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification, in which- Figure 1 is avertioallongitudinal section. Fig. 2 is a side elevation,showing the flange ofthe lid encircling the outer Walls of the kettle.

The object of this invention is to provide a boiler or other vessel forcooking sauerkraut and other strong-smelling articles, whereby theeffluvia therefrom will be carried into the fire, and thence up thechimney into the open air, preventin g the ofl'ensive odors from beingdiflused throughout the house.

The nature of the invention consists in the peculiar construction andcombination of means for carrying into effect the object stated.

In carrying my invention into effect I arrange in one side of thevessel, and on the in ner side of the wall thereof, a pipe or tube,which, when it meets the bottom of the vessel, is bent or deflected tillit reaches the center thereof, where it communicates, by an opening insaid bottom, with the fire. The lid of the vessel has an opening,forming a communication with the interior, from which leads a pipe ortube, registering with that above described, located in the boiler.

The steam and odors arising from the article being cooked pass upthrough the opening in the lid, thence through the pipe proceedingtherefrom to the tube in the boiler, whence it passes out of the openingin the bottom of the vessel into the fire. The draft in the fireproduces a suction in the tubes, drawing the steam and odors through thelatter into the flames, and thence up the flue or chimney.

Referring to the accompanying drawing, A shows a boiler or other similarvessel, to the inner side of the walls of which is attached or formed apipe or conduit, B. This conduit bends or deflects when it meets thebottom (J, proceeding along the latter until it reaches the center or anapproximate point, where it forms a communication with an opening, 0, insaid bottom.

D shows thelid,having an opening, 01, forming a communication with apipe, E, which is bent so as to pass through thelid at e, and

enter the conduit B. The steam and odors from the vessel pass throughthis system of pipes and openings into the fire, and up the chimney outinto the air, preventing the pollution of the atmosphere in 'the houseby the efliuvia of sauerkraut or other noisome-smelling substance.

The flange d of the lid may be made to slip outside of the walls of thebody A, as shown in Fig. 2, thereby rendering the said lid tighter, andpreventing the escape of the steam and odors around the edgethereof whenthere is not a sufficient draft in the fire to produce a current in thetubes. 1

What I claim as my invention is- In combination with the vessel A,having its lid and bottom centrally perforated at de, respectively, thetube B, soldered to the inner surface of the vessel, and having theradial extension 0, and the tube E, soldered to the outside of the lid,and communicating with tube B by steam-tight joint, as shown anddescribed.

In testimony that I claim the foregoing I have hereunto set my hand this10th day of November, 1875.
